Attacking ND arrays

[Ryan Peterson]

Is there a "good" way to take 2d slices of ND matrices, either in 
octave-forge or upcoming in future versions of octave?  Say I have a 4d 
matrix named foo with 5 values in each direction and I want to look at a 
slice of it.  Intuitively, I went for this:

b=foo(4,3,:,:);
imagesc(b)

But got an error about transposing ND arrays.  I remember reading something 
about someone doing this within C but am curious if and how people have done 
this in octave.  The most straightforward method I can think of is a loop 
but that can be time consuming.  Any recommendations/suggestions?

Thanks,
Ryan Peterson
